I am using USBloader GX [latest revision] and up to now I had an WBFS partitioned HDD.
I am intrigued about the NTFS support, so I got another NTFS HDD and I got a couple of quick [I hope] questions

a. Do I just throw the .wbfs on the root dir of the HDD? Or I need to make a special folder? Someone mentioned a /wbfs/ folder. Is this correct?
b. would .iso files work as well? This has been mentioned as well, but it's not clear for me.
c. In case .iso files work on ntfs+usbloader, do botch scrubbed and non-scrubbed iso files work?
d. Lastly, I am using Simple WBFS file manager, and it only converts .iso to .wbfs by splitting them up to 4gigs. Is there a program that does not split the wbfs, since using NTFS, splitting is unnecessary.
